NOT a member?  Welcome! We are glad that you have "discovered" our site. We know many of you were searching the web to help you understand pieces of porcelain that you may have found among your mother's, aunt's, grandmother's collection of dishes.  Or, perhaps you were searching to learn more about Nippon. However you found us, we are glad you did and we welcome you.

Most of this website is available for the non-member to access. We especially encourage you to visit our Gallery which has great examples of Nippon. Quickly you will see that Nippon is wildly diverse with fancy pieces as well as beautifully made practical, every day serving pieces. On the Home page you will see a category named "Know Your Nippon." Hovering over this button will provide you with a plethora of information about Nippon - reproductions, care and cleaning, backstamps, techniques, and books on Nippon. The category of Backstamps is usually where most visitors will want to spend some time. It has 5 booklets that endeavor to cover as much as possible about marks found on Nippon era porcelain. It is helpful to know how these booklets were created. This entire website is based on the many books written by Joan VanPatton, one of the original founders of the INCC. In all of her Nippon books one can find a section of backstamps. The booklets in this site incorporate all of her marks in two of her booklets - The Backstamps of the Morimura Company and Marks Other Than Morimura Backstamps. The booklet, Newly Discovered Backstamps, contains marks that have been discovered since Joan's last book was written in 2005. Nippon Era Dinnerware contains sets of china with and without pattern names of the Nippon era. The last book - Dolls and Playthings Marks - contains information about the marks used on dolls and other items in the Nippon era.

After perusing this website you might consider joining our club. We encourage you to do this. Membership in the INCC will allow you to receive a copy of the fabulous E-Journal, which is packed with outstanding articles and information about Nippon. A copy will be delivered to your inbox once a quarter. Joining also gives you access to a plethora of historical information on Nippon that has been amassed over the 40 + years of the existence of the club. Lastly, you will receive an invitation to join us at our annual convention where we gather to learn about Nippon, meet others with like interests, and buy and sell in members' rooms where you will find amazing, rare Nippon pieces.

Also, membership will give you instant access to our Member Tools section which includes: Journals, Notebooks, The Nippon Spotter, INCC Newsletters, and more  - all sections are kept up-to-date and is the place to find  information about upcoming events.
